: Reduces the complexity for network operators who currently rely on custom scripts to "scrape" inventory data from diverse devices.

Below is a draft write-up based on the current shepherd documentation and architectural goals for this technology.

: Enabling controllers to automatically verify that all installed hardware matches the intended design.

is an initiative by the Network Management Operations (NMOP) working group aimed at creating a unified, lightweight approach to network inventory management. It addresses the fragmentation caused by multiple competing models (such as Entity-MIB or varied YANG models) by providing a consistent framework for querying hardware and software components. Key Objectives

: Rapidly identifying devices running specific software versions or hardware revisions impacted by security advisories.

: Tracking available slots and port densities across the network through a standardized interface.

Further details and the latest revisions of the concept can be tracked through the IETF Datatracker .

Testimonial

I chose CAE  to complete my ground school as I have sometimes struggled academically and felt that, to give myself the best chance, I should go to the best school. I haven't been disappointed. All of the instructors were excellent and were always happy to help me…I genuinely think that I would have done considerably less well in my exams if it hadn't been for CAE instructors. I could not speak more highly of them and would, and will, thoroughly recommend CAE as the best school.
